PiezoelectricityPiezoelectricity refers to a crystal’s ability to produce voltage when pressurized.Certain crystals will actually produce a voltage when their crystal lattice is under pressure of any sort and that’s why we can use them in different ways in technology. (quartz watches for example)

Some crystals that are known to do this are quartz, topaz + any type of tourmaline.When I say “quartz”, I mean all types of quartz—not just clear quartz; so that includes amethyst, agate, citrine, rose quartz, etc.

Pyroelectricity“Pyro” means fire, so it has to do with temperature. Specifically, it’s the ability of a crystal to produce voltage when heated or cooled. (imaging, infrared detection) And quartz, again, has the ability to do this, as does tourmaline…. any kind of tourmaline. Even, indicolite, which is a teal blue or blue tourmaline.

TriboluminescenceThe property of the crystal to actually be able to produce light when it’s struck.And it doesn’t just produce light on the outside, like friction blowing out a spark, but internally, as well as externally; it produces this flash of light! So it’s not simply explained away as friction.

Crystals that are able to express triboluminescence are: quartz, diamond, and fluorite.I feel that crystals that have these properties are more powerful than crystals that don’t. And that just simply comes from experience working with them, as well as research and experience of my mentor. They’re all crystals that are relatively easy to find.If you’ll notice, quartz possesses all three of these properties:

piezoelectricity

pyroelectricity

triboluminescence.

It has other properties as well. In addition, it’s a silicate mineral, which happen to be the most abundant minerals on the Earth’s crust. (More than 90% of our planet’s crust is composed of silicate minerals.)

I feel like it’s no coincidence that quartz, in all its many forms--rose quartz, amethyst, citrine, green aventurine, clear quartz— is so accessible to us; both plentiful & relatively low-cost. All the jaspers and all the agates are quartz-based minerals that we can work with as well.

So, to finally answer the question:In my opinion, quartz (any kind of quartz), is the “A” number one most powerful crystal, and then 2nd would be tourmaline, and then thirdly I’d place topaz.I feel crystals that have these special properties are the most powerful ones because this allows the crystals to more easily tap into the body’s voltage and polarity.​Again, “what crystal is most powerful” can be up to personal interpretation… it’s a matter of opinion & experiences, and it can be very subjective based on the work that you’ve done and other crystals or minerals that you’ve worked with that you found to be very powerful. Maybe malachite is the most powerful one for you. The best thing to do is to develop a personal relationship, spend time with and really get to “know” your crystals.
